Answer: Oceans
Explanation:
Climate is primarily determined by the interaction between air and ocean. The warm wind circulate and makes the temperature feasible for life.
Oceans heat the air above it and it circulates from the equator region to the polar region to make the temperature optimum. The circulation of air due to ocean leads to climate change.
hence, these two factors are responsible for the climate of a region.
Answer:
Compliment system also known as the compliment cascade is a system of plasma proteins that are directly or indirectly activated by pathogens or pathogen-bound antibodies leading to a series/cascade of reactions. The outcomes include;
a) Opsonization
An immune response where the target pathogen is marked for ingestion by the phagocytes. where;
- C3b fragments bind to the surface of pathogens.
-
Macrophages and neutrophils are attracted to C3 protein molecules bound to the pathogens, making them easier to phagocytize.
b) Inflammation stimulation
An inflammation to attract more phagocytes.
- C5a fragments recruit immune cells to the site of infection.
- Neutrophils are attracted to the area and arrive via diapedesis.
- C3a fragments act as chemotactic agents.
c) direct cell lysis
Involves the attack on the pathogen hence eliminating it.
- C9 is polymerized into a circular-shaped complex on the pathogen surface.
- Multiple transmembrane proteins are recruited to the pathogen.
- MAC introduces holes to the bacterial cell membrane.
Answer:
Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Answer:
Matter is made up of small particles that are too small to be seen, even with a powerful microscope.
For most ecosystems SUN is the ultimate source of energy, and energy leaves the ecosystem in the for of ORGANIC MATTER.
